NSD is providing site assessment, design, permitting assistance, public outreach and construction supervision for the design-build effort to remove the fifty-foot tall concrete dam impounding over 1 million cubic yards of sediment in a 60 acre site. NSD staff will monitor sediment evacuation from the site and adapt the design to accommodate subsurface conditions to restore over a mile-long network of meandering stream channels and floodplain, restore a naturally-functioning channel through the dam site and supervise helicopter installation of several log jams upstream of the reservoir.
